I feel like soccer players have a different body type than a lot of the athletes in the US's big 3 sports. We're talking about a game that is all about endurance and dexterity IMO. A lot of these guys look more like marathon runners than football players. I guess WR's and DB's in football and then guards in basketball would be best suited. I agree to an extent with OP, but I also feel like it is a tired statement by Americans to excuse our shittiness in soccer.
